Abstract: An apparatus is provided that includes a string of power sources and step-down circuitry. The power sources are connected in series to provide a first voltage rail at a first voltage, and the string of power sources is divided into power-source segments. The step-down circuitry electrically is configured to provide a second voltage rail at a second, lesser voltage. The step-down circuitry includes control circuitry configured to monitor states of charge of the power-source segments, and control selection of one of the power-source segments to deliver an output from which the second voltage rail is provided, based on the states of charge. One or more first electronic components are electrically coupled to the first voltage rail, and designed to operate at the first voltage. And one or more second electronic components are electrically coupled to the second voltage rail, and designed to operate at the second voltage.

Abstract: A method is provided for horizon detection. The method includes acquiring an image that depicts a view of an environment, and defining a line pattern of lines that divide the image into respective pairs of image segments. The line pattern is formed of lines that are parallel, or intersecting at a common point of intersection. The method includes searching the lines of the line pattern to identify one of the lines as an estimated true horizon in the image that divides the image into a respective pair of image segments at a boundary of greatest difference in average brightness between the image segments from among the respective pairs of image segments. The method includes determining true horizon in the image from the estimated true horizon. The method may also include an evaluation of the estimated true horizon or the true horizon as to verify one or more expected characteristics.

Abstract: A method is provided for supporting an aircraft to execute a mission in which the aircraft maneuvers in an airspace system. The method includes detecting a lost-link event in which a datalink between the aircraft and a control station is interrupted or lost, and responsive to which the aircraft is preconfigured to execute a procedure. The method also includes conveying an intent of the aircraft to execute the procedure over a radio channel assigned for voice communication in the airspace system. In this regard, conveying the intent includes composing a message that indicates the intent of the aircraft to execute the procedure. The message is applied to a text-to-speech engine to convert the message to a corresponding verbal message in which the intent of the aircraft is conveyed. The corresponding verbal message is then sent over the radio channel assigned for voice communication in the airspace system.

Abstract: An aircraft and a control system for the aircraft includes a tilt-wing defining an inlet configured to receive air and an outlet in fluid communication with the inlet such that the outlet is configured to expel the air. The control system includes a high-lift device coupled to at least one of a leading edge, and a trailing edge of the tilt-wing. The high-lift device is movable relative to the tilt-wing. The control system includes a compressor in fluid communication with the inlet and the outlet. The compressor is configured to increase pressure of the air that is expelled out of the outlet. The outlet directs the pressurized air toward at least one of the high-lift device and a center section of the tilt-wing to maintain attachment of airflow across the tilt-wing. A method of operating the control system of the aircraft occurs to maintain attachment of airflow across the tilt-wing.

Abstract: A method for controlling an aerial vehicle including a compliant arm mechanism is disclosed. A propulsion system of the aerial vehicle is controlled to fly the aerial vehicle to an area proximate to a surface. One or more of the propulsion system and the compliant arm mechanism are controlled such that the compliant arm mechanism contacts the surface. The compliant arm mechanism is configured to extend laterally beyond a perimeter of the propulsion system. One or more sensor signals indicating contact of the compliant arm mechanism against the surface are received via a sensor. A force at which the aerial vehicle presses against the surface is determined based on the one or more sensor signals.

Abstract: An autonomy system for use with a vehicle in an environment. The autonomy system comprising a processor operatively coupled with a memory device, a plurality of sensors operatively coupled with the processor; a vehicle controller, a situational awareness module, a task planning module, and a task execution module. The situational awareness module being configured to determine a state of the environment based at least in part on sensor data from at least one of the plurality of sensors. The task planning module being configured to identify, via the processor, a plurality of tasks to be performed by the vehicle and to generate a task assignment list from the plurality of tasks that is based at least in part on predetermined optimization criteria. The task execution module being configured to instruct the vehicle controller to execute the plurality of tasks in accordance with the task assignment list. The task execution module may be configured to monitor the vehicle or the vehicle controller during execution of the task assignment list to identify any errors.

Abstract: A method is provided for detecting and avoiding conflict along a current route of a robot. The method includes accessing a trajectory of the robot on the current route of the robot, and a predicted trajectory of a nearby moving object, and from the trajectory and predicted trajectory, detecting a conflict between the robot and the nearby moving object. Alternate routes for the robot are determined, each of which includes an alternative route segment offset from the current route, and a transition segment from the current route to the alternative route segment. Routes including the current and alternative routes are evaluated according to a cost metric, and a route from the routes is selected for use in at least one of guidance, navigation or control of the robot to avoid the conflict.
